[encrypted-media] Be more explicit about the implications of empty robustness strings

ddorwin has just created a new issue for 
https://github.com/w3c/encrypted-media:

== Be more explicit about the implications of empty robustness strings
 ==
The 
[definition](https://w3c.github.io/encrypted-media/#widl-MediaKeySystemMediaCapability-robustness)
 of the `robustness` dictionary member currently says, "The empty 
string indicates that any ability to decrypt and decode the content 
type is acceptable."

To help authors (and discourage use of the empty string), the spec 
should more explicitly state the meaning of "any ability" and possible
 implications, which may include configuration of the CDM (see #177) 
to the lowest robustness level the Key System supports.
